My invention relates to an improvement with a tube for injecting fluid into the canal between thebladder and the stricture, and

embodies meansfor directing outwardly along the canal the cleansing fluid from the syringe for the` purpose 4of removing the causes of the stricture.

This invention includes the provi-sion of means to lock and hold a terminal penumatic y casing upon the nozzle of a perforated tube and in theprovision` of means for dispensing iuid from within the` tube eXteriorly and rearwardly thereof, passing the stricture for washing, cleansing and removing conditions causing the same.v

A further obj ect of my invention is to provide a sanitary urethral syringe which will work with rapidity, accuracy and ease and at relatively small expense.A v

An advantage isthatth'orough cleansing and medication of the urethral canal may be secured without allowing any of the injected fiuid or emanations` from the diseased canal to pass into the interior passages or cavities of the patient.

It is understood that the apparatus herein disclosed is merely suggestive of. a type of apparatus that maybe employed in carrying out the new method of operation, and that other suitable apparatus of different construction and arrangement of elements may be employed within the spirit and scope of the invention. j

An object of the invention is to makeA provision whereby the patient may apply the instrument to use and may seal and maintain forany desired time,the urethral canal between theradial discharge nozzle and the inner urethral passage so that the injection of the cleansing or Vmedicated liquid may be longy contained without the attention of a physician and without serious inconvenience to the patient.

,A feature .in this respect ,1S the use f a compressible pneumatic or air bulb of rubber or the like, and a thumb screw compressor for the bulb so that inflation of the `cover cap or casing overv the air nozzle can be held inflated to the required degree for the desired time without inconvenience to the patient. h Other objects, advantages and features of invention may appear from the accompanying drawing, the subjoined detailed description and the appended claims.

The accompanying Vdrawing lillustrates the invention.

Figure 1 is a top view of a syringe con- Structed in accordance with this invention.`

Fig. 2is anvaxial section on line m2, Fig. 1. Fig. 3 is an enlarged detail of the nozzle vand bulb.

1 is an injecting tube provided nea-r one end with perforatlons 2, forming a radial nozzle or outlet and provided beyond the outlet with a reduced portion 3 and plugged bythe neck 4 of a smooth head having an expanded shoulder 5 and a reduced terminal .nozzle 6. An

expansible cap 7 is fixed to and encloses the lterminal nozzle air tight, Vand is shown as an indla rubber bulb stretched over the head and retained by a collar 8clamped in position by a nut- 9 screwed onto the threadedportion 3 of the injecting tube. j

Extending from the nutand in spaced relation with the tube 1 overhanging the perforations 2, is the skirt 10 provided with a contracted terminal VV11, thereby forming a fluid chamber with the tube 1 providing a path for the travel of the iiuid within the tubev .through the perforations within the skirt vPreferably securedA to the bushing 14 by the jaws 16 is the stirrup 17 embodying the bar 18 in which is mounted athumb screw 19 provided with a compressor 20 to act uponthe air compressor gbulb 21, the neck of which is .Sealed on and 010611 C0 the nipple la Themes 23 ot the air compressor bulb 21 is secured to the nipple by the band 24 oi wire.

Piping extending along inside the tube and registering with the mouth of the nozzle 6 and the confnnunicating channel or bore 26 of the bushing 14 and the nipple 15, forms a continuous connection between the air compressor bulb 2l and the cap T to inflate the cap.

The tip of the tube with the inflated cap thereon can be inserted into the urethra while the cap is deflated. rlhen by compressing the bulb air is forced into the cap to inflate it to close the urethra at the mouth of the bladder.

The tube 1 is shown provided with a nipple 27 which is adapted 'for attachment to a tube leading from a supply of cleansing liquid y which is conducted through the tube 1 about the piping 25 and through the perforations 2, past the guiding skirt 10 and the contracted terminal 11 back along outside the tube and rez'irwardly thereof and inside the urethral canal.

Preparatory to inserting the tube the casing or cap 7 is lubricated and inserted into the canal past the stricture. After the insertion and positioning ot the cap beyond the diseased zone,the thumb screw is turned to compress the bulb 21 thus inlating the cap thereby sealing entrance to the bladder.

Following the adjustment of the tube and the inflation of the cap the water supply not shown, is connected with the nipple 27 and the fluid is permitted to run into the tube 1 and through the pertorations 2, discharging past the skirt 10, increasing its velocity by reason ot' the contracted guiding terminal 11 passing the stricture, cleansing and removing the con d itions ca using the same.

ln p factical manufacture the receiving end oi. the air pipe 25 will be bent as at 25 the inner end of the tube 1 will be spun down as at 1, and the radial nozzle holes 2 will be bored close to the reduced end 1a, and a hole lb for the bent end 25 oi the air pipe 25 will be bored in the side of tube 1 at such distance trom the reduced end 1u as will be required Jfor properly inserting the tube so as to bring the radial nozzle formed by holes 2 beyond the diseased parts ot the urethral canal the head is properly formed with the air nozzle as shown and is bored as at 6 to seat the inner end of the air pipe 25, and the neck 4 is provided with the end socket 4l to seat the reduced end 1a of the tube; the sleeve 13 as described. is also provided to lit the tube; the

distensible cap, capsule or cover 7 and other parts are also provided ready for assembly.

The inner end of pipe 25 is then inserted into the bore 6 and secured with, solder, not shown; the tube l is then brought over the pipe 25 and its reduced end la is seated in the socket il and the tube is adjusted to bring the air hole 1b into register with the mouth of the bent end 2. of the air pipe, and such end is secured by solder.

The cover 7, is then stretched over the nipple and the collar is brought into position around the neck to compress the neck of the cover against the head, and then the nut 9 and with the attached skirt 10 thereon is screwed onto the threaded neck l ot' the head to force the collar onto the neck of the cover 7.

The sleeve 13 is brought into position on the tube with the bore 26 in register with the mouth 1h of the air pipe, thus the other parts are assembled in an obvious way and the instrument is ready tor use as above indicated.

The head is ot' small diameter so as to pass along the urethral canal easily until the stricture or diseased portions are passed g. then by setting the thumb screw to expand the cap with air from the bulb 21., the urethral canal is sealed against passage of liquid from the tube 1 and said liquid will flow out of the canal.

Any method ot' supplying liquid to the tube may be employed within the judgment of the manufacturer and pleasure of the user.

Then the cleansing has been eli'ected, the thumb screw is loosened to allow the bulb to expand, thus deflating the cap and allowing the instrument to be withdrawn and cleansed for reuse.

I claim 1. In combination with a tube having a flushing nozzle, and provided beyond the nozzle with. a head having a reduced tip, and a bore therethrough, an inflatable air-tight cover 'for said head and tip and a pipe longitudinally disposed wit-hin the tube and Open to the inside ot' the cover to inflate the cover, means to supply compressed air to the pipe tor intlating the cover.

2. In combination with a tube having a flushing nozzle, and provided beyond the nozzle with a head having a reduced tip, and a bore therethrough, an inllatab'le air-tight cover for said head and tip and a pipe longitudinally disposed within the tube and open to the inside ot the cover to inflate the cover, means to supply compressed air to the pipe for inflating the cover; and a dellator secured to the tube beyond the flushing nozzle and the head.
